Pentagon scientists working inside a secretive unit set up at the height of the Cold War have created a microchip to be inserted under the skin, which will detect COVID-19 infection, and a revolutionary filter that can remove the virus from the blood when attached to a dialysis machine. The team at the Defense Advanced Research Projects Agency (DARPA) have been working for years on preventing and ending pandemics. One of their recent inventions, they told 60 Minutes on Sunday night, was a microchip which detects COVID infection in an individual before it can become an outbreak. The microchip is sure to spark worries among some about a government agency implanting a microchip in a citizen. Retired Colonel Matt Hepburn, an army infectious disease physician leading DARPA's response to the pandemic, showed the 60 Minutes team a tissue-like gel, engineered to continuously test your blood. 'You put it underneath your skin and what that tells you is that there are chemical reactions going on inside the body, and that signal means you are going to have symptoms tomorrow,' he explained. 'It's like a "check engine" light,' said Hepburn. Troops are likely to be highly skeptical of the new invention. In February, The New York Times reported that a third of troops have refused to take the vaccine, sighting concerns that the vaccine contains a microchip devised to monitor recipients, that it will permanently disable the body's immune system or that it is some form of government control.
